Security in relation to technology mediated communication is a multidimensional term which encompasses a multitude of different issues. It reaches into the areas of privacy protection on the net and consumer protection in connection with e-commerce. It also reaches into the area of cyber crime, including protection against illegal and harmful content. Furthermore, it is connected with the protection of state institutions against information breaches, which conversely can be in conflict with privacy protection etc. In the present sub-section, however, only the issue of the network and information security, i.e. the technical aspects and their regulatory implications, is touched upon. Even this is an issue with many different dimensions.
